要点:氟,电极,机理,氟化镧。简介: 我们用Orion的94——09和94——09A氟电极测定了电荷输送到氟化镧晶体的机理。当氟电极放在加有(F～(18))或没有(F～(18))的15％NaAC溶液(pH 6.3)里并加一定电压时,我们由此得出结论是电荷传导到氟化镧的机理是一种离子的扩散。F～(18)很迅速地集聚在电极表面上,扩散到氟化镧体中(深于300A)也是很迅速的。众所周知,碱金属卤化物含有schotty空穴,LaF_3在27℃时是由0.1％中性sch——
Key points: fluorine, electrode, mechanism, lanthanum fluoride Description: We measured the mechanism of charge transport to lanthanum fluoride crystals using Orion’s 94--09 and 94--09A fluorine electrodes. When the fluorine electrode was placed in a 15% NaAC solution (pH 6.3) with (F ~ (18)) or no (F ~ (18)) and a voltage was applied, we concluded that the charge was transferred to the fluorine The mechanism of lanthanum is a kind of ion diffusion. F 18 precipitates very quickly on the surface of the electrode, and diffuses into lanthanum fluoride (deeper than 300 A) very quickly. It is well known that alkali metal halides contain schotty holes, which at 27 ° C consist of 0.1% neutral sch--
